My theory was that cupping would create ridges that are somewhat "uni-directional." When slowing down without braking, these ridges would be more in play with the tire bringing the car down in speed rather than accelerating or maintaining a constaint speed.
A wild *** guess on my part!
When I have experinced cupping on my motorcycle tires, I pick up more noise and a slight vibration in corners. Hence, my theory on car tires.
Good luck with finding the root cause!

Did you start noticing it all of a sudden, or after hitting a large pothole or something? Or did you let somebody drive your car, like a valet, etc? Anyway, if all your lugnuts are torqued properly, and your tires are inflated properly and not unevenly worn, and doesn't happen when braking, it has to be suspension/steering related. Could be the alignment, a bad bushing, a loose nut, etc. You'll need somebody who knows what he's doing to drive the car and diagnose the issue. Doesn't sound like a big deal, but the hard part is to find out what exactly is causing it. Good luck.

What happens when you do apply light braking? Does it get more pronounced or does the vibration lessen? If it lessens that would signal more of a tire only issue (check tread, sidewalls and pressure). If it gets worse, that could point to more of a wheel or alignment type issue.

I get a vibration acelerating/crusing starting at about 55-60 then stops. It is not a steady vibration as it happens as almost a cycle? Then back at around 80....

I my experience, that was my culprit…I had the wheels road force balanced using a hunter machine and all was well. I know there could be a multitude of things, but could be a good place to start. Idk how old your tires are or mileage

No problem. Hope that’s it. Also, your tires are getting close to being very old…could play into it. I had that issue as well when I bought mine…tires were ‘new’ but date code was 10 years old
